Use of gettext in scripts
Here's a question. In a C program, it makes sense to have a command
printf(gettext("I am a %s, what are you?\n"), name);
for then the translations will place the noun (represented by %s) in
the appropriate place in the translation. (This may be a silly
example, but it will suffice.)
But what would the equivalent be in a shell script or a Perl script?
The following "solution" doesn't work, because the substitutions
happen before gettext sees the string:
sh: gettext -s "I am a $name, what are you?"
perl: print gettext("I am a $name, what are you?\n");
and these don't because the word-order is not guaranteed to be the
same in all languages:
sh: gettext -n -s "I am a "; echo $name; gettext -s ", what are you?"
perl: print gettext("I am a "), $name, gettext(", what are you?\n");
So the following looks like a possibility, but it's a bit yucky:
sh: text=`gettext -s 'I am a $name, what are you?'`
eval echo $text
perl: $text=gettext 'I am a $name, what are you?';
eval "print $text, '\n'";
Here's the question: is there any standard, preferably nicer, way of
handling strings containing variables in shell or Perl scripts?
